Title: Process for preparing precursors of polyimidazoles and polyimidazo pyrrolones
Inventor: AHNE HELLMUT DR
IPC: C08G73/10
Filed: 1984-12-12
Granted: 1987-04-09
Abstract: Oligomeric and/or polymeric radiation-reactive polyimidazole and polyimidazo pyrrolone precursors which are soluble in organic solvents, can be prepared with high purity, i.e., especially without chloride, in a simple manner if an aromatic and/or heterocyclic tetraamino compound is reacted in the presence of a carbodiimide, with an olefinically unsaturated monocarboxylic acid and a dicarboxylic acid, or with an olefinically unsaturated monocarboxylic acid and an aromatic and/or heterocyclic tetracarboxylic acid dianhydride, or with an olefinically unsaturated tetracarboxylic acid diester, in the form of an addition product of the tetracarboxylic acid dianhydride and an olefinically unsaturated alcohol. The radiation-reactive precursors prepared in this manner are suitable, for instance, for the manufacture of highly heat-resistant relief structures.

Granted: 1989-02-23
Abstract: The cooling machine or heat pump has a thermoacoustic work system having a heat source and a heat sink coupled with at least one thermoacoustic drive system of like construction. The heat source of the drive system has a higher temperature than the heat source of the work system. The machine can be used in a refrigerating system with heat energy removed from a cold chamber and used as a heat source in the thermoacoustic work system. The machine can also be used in a heat pump heating system with heat energy removed by way of a first heat exchange surface from a burner and used as a heat source in the thermoacoustic drive system. A process water circuit is used as a heat sink for the thermoacoustic drive system while a heating-water circuit is used as a heat sink for the thermoacoustic work system.

Title: Method and device to delay an ultrasonic signal
Inventor: HILLER DIETMAR DR
IPC: G01S7/523
Filed: 1985-07-16
Granted: 1989-06-01
Abstract: In medical ultrasonic technology (in particular with phased arrays) it is necessary to delay in time a plurality of received ultrasound signals and subsequently to add them after they are as nearly in phase as possible. The delay times required for this purpose are approximately between 0 and 10  mu s. The ultrasound signal is analyzed as to envelope and a sign. The envelope is then delayed either in analog (e.g. with LC delay lines) or digitally (e.g. with shift registers) through a delay means which is adjustable in coarse time steps of e.g. 500 ns. The sign signal corresponding to the sign of the ultrasound signal is delayed via a digital delay section which is adjustable in small time steps of e.g. 50 ns. Phase coherence to other ultrasound signals can be established. Thereafter the delayed sign signal and the delayed envelope signal are multiplied one by the other in a multiplier. Thereafter the output signal is filtered in a low-pass filter. The output from the low-pass filter then represents the delayed form of the ultrasound signal.

Abstract: The cryogenic pump operates in two stages, utilizing a supercharging part and a high pressure part. These two parts are comprised of a high pressure piston pump (3, 4, 34, 35) and a supercharger (5, 6, 61, 62) disposed in a tandem relationship and sharing a common piston rod (8). The supercharger is enclosed in a heat insulated intermediate container (7) and delivers the liquid cryogenic fluid to the high pressure cylinder. The pump operates to convey a liquid cryogenic fluid such as liquid nitrogen, for example, at a high pressure through evaporating means into pressure resistant commercial steel cylinders where the gaseous nitrogen is kept at a pressure of 200 bar and ambient temperature.

Abstract: A cleaner has in a tank a vacuum pump protected by a float valve above the maximum possible water level and a submersible pump at the bottom and both of these in the tank produce a vacuum for the suction of water against the vacuum, the submersible pump moving the filtered water collected in the lower region of the tank out of the tank past a check valve. The vacuum pump is constructionally combined with a tank cover, so that it can be mounted on differently constructed tanks for different cleaning functions. For wet suction purposes, the associated paper filter bag has a passage opening for the suction connecting pieces, so that the water to be filtered passes through the filter from the inside to the outside.

Abstract: A monoclonal antibody is produced which is specific for a cell surface antigen found predominantly on human mammary tumor cells. Animals are inoculated with human mammary tumor cells or cell material, and spleen cells obtained from the animals are fused with myeloma cells to produce hybridomas. The hybridomas are cultured as monoclones, and antibodies obtained from the individual clones are tested for their reactivity with several human mammary tumor cell lines and mammary tumor tissues. A clone which produces an antibody that reacts generally with human mammary tumor cells but not other tumors, such as mesotheliomas, is selected for further culturing to produce the antibody, and the antibody is obtained from the culture growth medium or from ascitic fluid of an animal bearing a tumor of the hybridoma. The antibody is useful in diagnosing mammary tumors.

Abstract: A memory system for storing and retrieving data sequences of symbols in response to a query sequence is disclosed. Each of the sequences is made up of three types of symbols, constants, delimiters, and variables. A data sequence is retrieved in response to a query sequence if the two sequence can be made identical by replacing the variables in each sequence by constants or combinations of constants and delimiters, the combinations beginning and ending with a delimiter. To reduce the time needed to search the memory for all data sequences corresponding to a given query sequence, multiple processing units are employed. In addition to carrying out rule-based searches, the memory system can efficiently retrieve all records containing a specified list of key words.

Abstract: Methods are disclosed for operating receiver devices which take serial data patterns off a high speed synchronous serial transmission media and covert the data to parallel pattern outputs. According to the invention, each device operates under a "permission to capture" data protocol which allows a given receiver to operate at the byte rate of the transmitted data. Devices using the disclosed methods may be operated individually or in a cascaded fashion, In either mode, by enabling the receivers to transfer high speed data at the transmitted pattern byte rate, as opposed to the bit rate, the reliability and capacity of the receivers to field high speed data is enhanced. In addition, the disclosed methods obviate the need for receivers operating in a cascade mode to "know" their position in a cascade chain. As a result the operating simplicity and reliability of devices that employ the disclosed methods is further enhanced.

Abstract: Seasoning composition is produced with a method,, which comprises coating fine particles of sparlingly water-soluble 5 min -ribonucleotides having a total water content of 12 to 20 weight % and a particle diameter not exceeding about 150  mu m with an oil/fat and/or a wax melting at a between about 55 DEG C to about 90 DEG C. The thus obtained seasoning composition causes very little cracks or gaps on the surface of coated particles even after storage for a long time. Accordingly this composition is applicable with advantage to foods because of good protection from degradation of 5 min -ribonucleotides due to phosphatase.
